I just changed the front and rear diff fluids a couple weeks ago and after seeing that the rear is just a cap the pushes in for the fill plug I really want something threaded and was looking for what the best bang for my buck would be.

Added protection is not a requirement, just added benefit. I want something more than just a push in plug
